  1. 1. Structural controls and associated alterations in the West Maurliden volcanic-hosted massive sulfide deposit, Skellefte district, northern Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Nikolay Zhivkov; [2021]
    Nyckelord :West Maurliden; volcanic-hosted massive sulfide deposit; Skellefte district; Structure;

    Sammanfattning : Volcanic-hosted massive sulfide (VMS) deposits are one of the main sources for zinc, copper, lead, silver and gold in Sweden. The majority of VMS deposits in Sweden are located in the Bergslagen region and the Skellefte district (Fig. 1). LÄS MER

  3. 2. GEOCHEMICAL UNDERSTANDING OF VANADIUM IN MALMBERGET ORES (KIRUNA TYPE), NORTHERN SWEDEN

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Kabelo Kambai; [2021]
    Nyckelord :Vanadium; Malmberget; Kiruna Type;

    Sammanfattning : The Norrbotten region is an important Swedish mining district with occurrence of several economic deposits and sub-economic deposits of apatite iron ores (Kiruna Type) and epigenetic Cu-Au ores. The apatite iron ores include the large Malmberget deposit mined by LKAB company as one of their world class underground mines. LÄS MER

  4. 3. Assessing a Modeling Standard in Volcanic-Geothermal Systems: the Effects of the Lower System Boundary

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shelly Mardhia Faizy; [2021]
    Nyckelord :Geothermal; Numerical Modelling; Laccolith; Permeability; Topography;

    Sammanfattning : Geothermal energy consumption is projected to increase along with other renewable energy in the future. Therefore, it is important to have a better understanding on the evolution of geothermal systems to optimize the exploitation of such resources. Generally, numerical models are used as a fundamental tool to study a potential geothermal field. LÄS MER

  5. 4. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Marcus Eriksson; [2020]
    Nyckelord :Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Sammanfattning : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. LÄS MER

  7. 5. Volcanic facies and hydrothermal alteration at the Norra volcanigenic massive sulfide deposit : Storuman area, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Meseret Gebreyesus; [2020]
    Nyckelord :Volcanic massive sulfide deposit; alteration zonation; volcanic chemostratigraphy; facies architecture;

    Sammanfattning : The Skellefte District, with a long and rich history of base metal extraction that commenced asearly as 1924, is rated amongst the leading mining provinces in Sweden and Europe. The districtrepresents a Paleoproterozoic volcanic arc hosting more than 85 known (gold-bearing) VMSdeposits and several economic grade orogenic gold occurrences. LÄS MER
